I don't have any experience with Dymaxion, but if you're interested in an adaptable schedule, this worked for me:

- Midday Nap (23 mins)
- 6pm - After Work/School Nap (23 mins)
- 10pm nap (flexible, can be left out sometimes) (23 mins)
- 3am-6am core (3 hours)

Another alternative that I know some other people prefer, but has me struggling during the night, is to nap from 11pm to 2am:

- Midday Nap (23 mins)
- 6pm - After Work/School Nap (23 mins)
- 11pm -2am core (3 hours)
- 6am nap (23 mins)
